freebsd stable - Mar 2008 - FreeBSD 7.9-stable: weird messages in /var/log/messages?

Hello
One one of my stable machines I see these messages in /var/log/messages:
Mar  3 18:37:41 kg-i82 kernel: 16.011e9e3975b3aa06 too long
Mar  3 21:41:42 kg-i82 kernel: 16.016a24cf0742715c too long
Mar  3 21:41:58 kg-i82 kernel: 15.feb784aee196608c too short

Does anyone know hwat the messages mean, or which part of the kernel
they are from?
Googling didn't help me.

The machine runs FreeBSD 7.0-stable:
tingo@kg-i82$ uname -a
FreeBSD kg-i82.kg4.no 7.0-STABLE FreeBSD 7.0-STABLE #1: Sun Mar  2
01:18:27 CET 2008     root@kg-i82.kg4.no:/usr/obj/usr/src/sys/I81K  i386

and the complete /var/log/messages looks like this:
tingo@kg-i82$ less /var/log/messages

The only "unusual" thing is that the machine has been booted verbose.

It is reporting large variations in the rate of your time clock (see 
kern_tc.c).

Also, you appear to be emailing from the distant future.  Please reply 
with stock tips :)
